Furnace Replacement

Sometimes a repair is not sufficient to fix your furnace. At times a new furnace is the most cost and energy efficient solution. Performing repairs or service on a system in need of replacement is counter productive and costly. We will always help you to determine whether a repair or replacement is the best option.

If you do need a furnace replacement, we know how overwhelming it can be. Here are some of the frequently asked questions about furnaces that we get from some of our Hudson, MA residents:

What Are The Different Types Of Furnaces?

Single Stage: A single-stage furnace has only one stage of operation. It can either be turned on or turned off.

Two Stage: A two stage furnace has two settings - full and half speed. This is a more efficient way to hear and provides more comfort by moving air at a slower pace.

Variable Stage or Modulating: Modulates the speed and heat output based on the temperature outside and the desired comfort level inside. This type of furnace is the most efficient as it only works as much as you need it to.

What Is AFUE?

AFUE, or Annualized Fuel Utilization Efficiency, is a measure of furnace-heating efficiency. The higher the AFUE, the more efficient the furnace.

What Size Furnace Do I Need?

We can calculate an appropriately sized furnace by determining how many BTU’s (British Thermal Units) are required to heat your home. Contrary to what you might think, a bigger furnace does not necessarily mean better or more heating power. Call us at Chaves HVAC, and we can set up an appointment to calculate the furnace size you might need.
